问题
In a Windows batch file, is it possible to get the text of date in some location independent form to get the location independent date stamp as a string? To make the question clear... In the Czech Windows, the wanted code looks like this:
d:\>date /t
čt 16. 05. 2019
d:\>echo %DATE:~-4%%DATE:~-8,2%%DATE:~-12,2%
20190516
However, in the English Windows the same code returns bad results for obvious reasons:
d:\>date /t
Thu 05/16/2019
d:\>echo %DATE:~-4%%DATE:~-8,2%%DATE:~-12,2%
2019/1u
If the code is tuned for the English Windows, then it does not work in the Czech environment. How it should be implemented?
回答1:
Here is a method you can manipulate the output of wmic os get LocalDateTime /VALUE
@echo off
for /f "tokens=1,2 delims==" %%i in ('wmic os get LocalDateTime /VALUE ^>nul 2^>^&1') do (
if ".%%i."==".LocalDateTime." set mydate=%%j
)
set mydate=%mydate:~0,4%/%mydate:~4,2%/%mydate:~6,2% %mydate:~8,2%:%mydate:~10,2%:%mydate:~12,6%
echo %mydate%
and in the specific format you seem to want it YYYYMMDD and excluding time:
@echo off
for /f "tokens=1,2 delims==" %%i in ('wmic os get LocalDateTime /VALUE ^>nul 2^>^&1') do (
if ".%%i."==".LocalDateTime." set mydate=%%j
)
set mydate=%mydate:~0,4%%mydate:~4,2%%mydate:~6,2%
echo %mydate%
